Indmar announced the first-ever Ecoboost marine engine to the marine industry. This engine is the newest addition to the suite of Indmar Marine Engines, the 2.3L EcoBoost by Indmar. The bold, uncompromising nature of the 2.3L EcoBoost was evident at first sight, even next to its head turning big brother, the ROUSHCharged Raptor 575. 

Ford introduced EcoBoost technology in 2011. Today, it can be found in various configurations across the Ford and Lincoln product line. The 2.3L application specifically powers SUV’s like the Lincoln MKC and Ford Explorer along with performance cars like the Mustang and Focus RS and off road vehicles like the all-new Ford Ranger and soon to be released Ford Bronco.  EcoBoost is a proven technology that continues to break new ground and today it’s opening new doors in the marine industry.
